matplotlib-users Mailing List for matplotlib (Page 5)

The subplot comma notation problem I was having seems to have gone away in
the latest Ubuntu distribution, which includes MPL 0.87-5.

Thanks,

I've already heard  a little bit of this package. Only problem is that ther=

is no installer yet if I didn't miss it, I would have to prepare an ebuild=

and also to install on windows too, something I never did. I don't know wha=

would be the faster for me, maybe going further with matplotlib directly,=20
maybe I'm wrong.

I eventually solved my problem and I can embedded in wx... which was trivia=
l=20
for examples, maybe because I'm quite new to OO programming etc.

wxglade6.py continously plots curves I hope it may help beginner like me to=
=20
embed matplotlib in a wxpython application which generally need the=20
possibility to update the curve plotted.

I just have one question : why is the wxTIMER passing 2 parameters to metho=
d=20
app.frame1.panel_graf?=20
I putted an dummy second parameter to solve this problem (without=20
understanding the reason for that!)

when printing the dummy_parameter it returns :
<wx._misc.TimerEvent; proxy of C++ wxTimerEvent instance at=20
_a4149bbf_p_wxTimerEvent>

So what?


Long live matplotlib!

The latest mpl is compatible with numpy-1.0, not the release candidates.

Infos on compatible numpy/scipy versions: http://scipy.org/Download

I'm not sure which numpy version is required by the latest mpl, but the 
latest tarballs should work. If you have numpy/scipy installed via a 
package manager, check the versions. If they are not too old, try to 
just upgrade mpl and see if it works, otherwise install (1) numpy, (2) 
scipy, (3) mpl.
Always remove/uninstall/backup the old installations first (to be on the 
safe side also everything in ~/.matplotlib, maybe back up your 
matplotlibrc file). Install to /usr/local/lib/python2.x/site-packages 
(instead of /usr/lib) with python setup.py install --prefix=/usr/local 
to avoid clashes with your package manager (I experienced such things).

Hi

sorry for the stupid question but I have installed an RPM version of
matplotlib and now I would like to upgrade it. Unfortunately I would
like to install a version that doesn't have an RPM.
I downloaded the source and built it, but I don't know if I can just
install it over the old version or if I have to remove the old version
and then install the old one ...
What should I do with Scipy and Numpy?

Is there some docs about this?

Thanks for the help

1. arrayrange() is a deprecated name. arange() is the preferred name.

2. However, arange() with floating point numbers is unreliable. Because of
floating point precision issues, it is often difficult to tell whether or not
the endpoint will be included. Use linspace() instead.

Hi,all:
How do I include the stop value in the array by using arrayrange?
Say:
arrayrange(0,10,1.0,Float)

Hi,



I didn't get the way to embed a plot where I wish it to be, for example
inside a panel or a sizer?

I did the following :
I create a panel panel_4 which is where I'd like to get the plot, I create a
sizer sizer_8 in it and try to load the plot but the plot does not show. I
don't know how to solve this ?


In the __init__ of the frame I put this :

class MyFrame(wx.Frame):
    def __init__(self, *args, **kwds):
        ...
        self.panel_4 = wx.Panel(self.panel_1, -1)
        #matplotlib part initialisation
        self.fig = Figure((6,6), 75)
        self.canvas = FigureCanvasWx(self.panel_4, -1, self.fig)
        self.toolbar = NavigationToolbar2Wx(self.canvas)
        self.toolbar.Realize()
        # Create a figure manager to manage things
        self.figmgr = FigureManager(self.canvas, 1, self)
        #...

        sizer_8 = wx.BoxSizer(wx.VERTICAL)
        #...

        sizer_4.Add(sizer_5, 1, wx.EXPAND, 0)
        self.panel_4.SetAutoLayout (True)
        self.panel_4.SetSizer(sizer_8)
        sizer_8.Fit(self.panel_4)
        sizer_8.SetSizeHints(self.panel_4)
        sizer_8.Add(self.canvas, 1, wxLEFT|wxTOP|wxGROW)
        sizer_8.Add(self.toolbar , 0, wxGROW)

The first time I "import pylab" after installing matplotlib
I get many warnings (below).  This is 0.87.7 under Python 2.5.
Is ignoring these the right thing to do? (I seem to be up and running.)

That is probably because you installed a matplotlib compiled against 
newer libraries (e.g. numpy and/or Numeric and/or numarray) than you 
have installed on your machine (although I think package dependencies 
*should have* prevented this).  If you build matplotlib from the tarball 
this will not occur--it will be compiled against the libraries that are 
on your machine.  As I said before, you will only need to install some 
devel packages from your present distribution so that you will have the 
corresponding headers.

Eric

I would encourage anyone running linux to simply build matplotlib from 
the latest release tarball.  It's easy.  You may need to install some 
devel packages first, but once you have stumbled over the missing bits 
and installed them, then forever after you can very easily update to the 
latest version whenever there is a release.  Matplotlib changes fast 
enough that this can be quite a help.

I think that what is actually happening here is a system-wide 
matplotlibrc file is being found and is providing the numpy value.

There are two issues here:

1) Only a single matplotlibrc file is read, and the search goes from 
nearest (current directory) to farthest (system-wide).  So if a 
parameter is missing from the matplotlibrc file that is found, it is 
filled in from the hard-coded defaults, not from a more distant 
matplotlibrc file.  This is simply the design, not a bug.

2) The hard-coded default (Numeric) is not the same as the matplotlibrc 
template default (numpy).  I consider this a bug.  It has become 
important now that matplotlibrc is being provided with almost everything 
commented out.  I think we need to sweep through mpl and update the 
hard-coded defaults to match the values that were being provided via the 
matplotlibrc file, on the grounds that the latter were probably the 
result of experience, the former the result of initial guesses.

Eric

Using the advice from Seweryn Kokot I was able to install matplotlib
0.87.7-0, but this resulted in all sorts of errors instead of a graph.
I'll just make do with matplotlib 0.82-5 for now.
Thanks for your advice!
Marius.

Unfortunately, 0.87-5 is only available in the 6.10 (Edgy) repositories,
so we'll have to upgrade to 6.10, request that matplotlib be backported to
6.06, or find a non-Ubuntu repository from which to install the latest
matplotlib package.  I plan on upgrading sometime soon, so I'll wait for
that.

Hello,

i try to write a module which evaluates various Data, and occasionally
creates a plot, which is returned to the user. At the discretion of the
user, he should be able to show selected plots. This is an example
module with two approaches for this problem:

-----------------
import pylab
import matplotlib

def makeplot1():
    pylab.ioff()
    fig = pylab.figure()
    spl1 = fig.add_subplot(211)
    spl2 = fig.add_subplot(212)
    spl1.plot([1,4,9,16])
    spl2.plot([1,3,5,7])
    pylab.ion()
    return fig

def makeplot2():
    fig = matplotlib.figure.Figure()
    spl1 = fig.add_subplot(211)
    spl2 = fig.add_subplot(212)
    spl1.plot([1,4,9,16])
    spl2.plot([1,3,5,7])
    return fig
----------------------

The user fires up ipython and imports my module:
ipython -pylab
>>> import plotgen

After analysizing various data, he wants to look at a particular plot:
>>> fig = plotgen.makeplot1()

Now can one make pop up this plot? I tried to make this figure current:
>>> figure(fig.number)
but nothing to see. Then:
>>> draw()
>>> ion()
Only show() works, but this pops up all figures defined, and this can be
a large number of figures if makeplot1() has been called often, or I
have many figures. I only want to see this particular figure.

So next try with the object oriented interface:
>>> fig = plotgen.makeplot2()
>>> figure(fig.number)
AttributeError: Figure instance has no attribute 'number'

Ok, this does not work. In a cookbook i saw that one needs something
like "canvas = FigureCanvasAgg(fig)". But i cannot use it: As writer of
module "plotgen" i dont know what backend (Agg) is used by the user. And
the user simply uses "ipython -pylab" and should not care about the
backend.

Whats the correct solution for my problem?

Best Regards,

Roman

    fig = pylab.figure()
    spl1 = fig.add_subplot(211)
    spl2 = fig.add_subplot(212)
    spl1.plot([1,4,9,16])
    spl2.plot([1,3,5,7])

    return fig

def makeplot2():
    fig = matplotlib.figure.Figure()
    spl1 = fig.add_subplot(211)

----------------------

The user fires up ipython and imports my module:
ipython -pylab
>>> import plotgen

After analysizing various data, he wants to look at a particular plot:
>>> fig = plotgen.makeplot1()

Now can one make pop up this plot? I tried to make this figure current:
>>> figure(fig.number)
but nothing to see. Then:
>>> draw()
>>> ion()
Only show() works, but this pops up all figures defined, and this can be
a large number of figures if makeplot1() has been called often, or I
have many figures. I only want to see this particular figure.

So next try with the object oriented interface:
>>> fig = plotgen.makeplot2()
>>> figure(fig.number)
AttributeError: Figure instance has no attribute 'number'

Ok, this does not work. In a cookbook i saw that one needs something
like "canvas = FigureCanvasAgg(fig)". But i cannot use it: As writer of
module "plotgen" i dont know what backend (Agg) is used by the user. And
the user simply uses "ipython -pylab" and should not care about the
backend.

Whats the correct solution for my problem?

Add the following line to your /etc/apt/sources.list:

deb http://debs.astraw.com/ dapper/

I have the same symptoms on my Ubuntu 6.06 using python 2.4 and
matplotlib 0.82-5. Where did you find matplotlib 0.87-5 though? It's not
in the repositories as far as I can tell. I use synaptic for upgrading.

Hi,

When I don't use a matplotlibrc file, the default numerix choice is numpy,=
=20
which is OK.

When I have a matplotlibrc, and I specify "numerix : numpy", everything als=
o=20
behaves as expected.

However, when I have a matplotlibrc, but one which does not contain=20
a 'numerix' statement, then my old version numeric gets picked up.

I assume this is a bug?

Try the plain "Agg" backend rather than e.g. GTKAgg or TkAgg.

Must matplot be run with a backend installed suppose I only want to create a
command line program and create plot and output as gif/jpg/png?

Because import is giving me errors seemingly in reference to x server:

Thanks for confirming that it works on another system.  As I'm currently
using 0.82.5, I suspect upgrading to 0.87.5 (apparently the latest
available through official Ubuntu repositories in the newest distribution)
will solve the problem.  I'll report back once I do this.  Any Ubuntu
users out there have a similar experience?

Cheers,
Josh
